I guess you must be frequently switching your headphones between the phone and some other device and so it is not sufficient to keep the $10 dongle attached to your headphone cable
No, I really just use the standard 3.5 mm EarPods to talk on the phone with family. But the conversations are long and it's much more comfortable to listen with the EarPods than to 'use the phone'. The conversations always begin with 'lemme rig up.'
But if you got a new phone it would come with EarPods with a lightning cable so it’s only different if your phone conversations last long enough that battery life is a concern
